I 5 chine, it is desirable to make sure that the The receiving knitting machine, referring to F1 1, may have any kind of needle cylinder or other carrier 1, grooved to guide needles a, and may be provided with any kind of web-holder bed 2 for any usual form of webholders w worked in and out between the needles, so that there is a wave a Fig. 2, of withdrawal of the hold-down hook parts w of the web-holders from a point following a rise or advance in the needles to take yarn, to a point following the substantial retractionto knit of the needles and at or immediately following their most retracted posi tion to knit, as usual. These motions of the web-holders are functions of cams in the machine of the Scott & \Villiams type shown, carried 011 a web-holder eam-cap 3, Fig. 3, and including a withdrawing cam 3 and advancing cam slopes 3". lVhatever the direction of relative motion of the parts, for example the cylinder 1 and bed 2, in respect to the cams, not shown, for operating the needles, and the cams on cap 3 for working the web-holders, the cap 3 is restrained from following by contact of one or the other of stops 3 against a fixed part 40, which may be a post fixing the closed or operative position of a latchring or yarn guide carrying element 5, horizontally pivoted on a fixed partto the left of Fig. 1, not shown, all as usual. This results in a web'holder wave of retraction, at 00, Fig. 2, for example, long enough in relation to the lost motion between 3 and 40 always to include a substantial angular space, for example corresponding to a part of the width of and opposite to a yarn-feeding throat 4: formed in the ring 5, which accommodates yarn-feeding yarn fingers, one of which is shown at 6 in operative position. The end of the yarn i supplied by finger 6 may be guided or clamped as usual on the upper face of an internal platform 7, slightly above the plane of intersection of the upper arms ofthe web-holders w and the surface defined by the needles, in which plane the fabric and new yarn is supported by. the web-holders, by a receiving guide 8 and clamp 9 pivoted at 10 on an over hung bracket 12 on latch ring 5. :l iracket 12 may also support a severing device ll for yarn y, and on the under face of the platform 7 projections 13 and 16 may as usual be relied upon to guide fabric, especially heels and toes, downward into the hollow .needle cylinder.

hen a transferred fabricsection Fig. l, is applied to the needles a, the pivoted latch ring having been lifted out of the way, it is customary first to level the needles a by removing acam operating them during a revolution of their carrier, and then beginning knitting movement of the needles and feeding yarn prior to the first needle moved. to knit, but whether or not this is done, all of the web-holders. except those in the withdrawal wave at w stand with their holddown hooks between. the needles, as shown at the right in Fig. 1. It is not desirable to rely 011 motion of the needles to position the fabric in proper relation to the web-holders, and the transfer device can not depress loops impaled on the shanks of the needles below the plane of the hold-down hooks ea. In large diameter machines in which there are no devices interiorly of the needle cylinder it possible for the operator to reach a hand from below to pull down on the fabric. Otherwise, weights have to be used before starting to knit to pull down the impaled edge to the position shown in Fig. 1. This is an uncertain operation, and the weights required often result in damaged fabric.

\Vhether the machine is required to knit on the first part of its motion after the latch ring is returned to OPQIHtlVB position, or whether it is provided not to begin opera tion of the needles to knit until after rotation has begun, this invention provides an instrument 20 to act on the transferred fabric at the beginning of rotary motion progressively to depress on the needles the fabric transferred below the level of the hold-down hooks of the web-holders, while the hooks of the web-holders are retracted, as at a), so that their iirst insertion thereafter is operative to thrust a hold-down hook over the transferred edge of the transferred fabric.

The instrument 20 may be of any suitable form to perform this operation. As shown, it includes a cam 21, Fig. i, held near the backs of the needles opposite wave (a, and preferably made as a rounded down-turned end portion of a horizontally placed arm fastened on platform 7, as by screws at 22 entering holes in a block 23, which may be the mounted end of the receiving guide 8 already on the machine. The uppermost normal extent of the instrument 20 is preferably not high enough to prevent delivery of yarn by a finger 6 below the hook ends of needles it, either at transferring or at normal knitting position of the needles. The normal clearance of the operating cam end 531 of the instrument above the upper edges of the inward arms of the web-holders w is suilicient only to accoinmmlate the expected thickness of the transferred fabric It will be apparent that, since this instrument is always within the wave a", the withdrawn webholders permit the edge of fabric 7' to be moved down the needle shanks to the correct position against the resistance of such parts of the transferred edge as do not readily slide onto the thicker parts of the needle, such as the cheeks at their latch pivots, without failure and without breakage.

What I claim is:

1. In a knitting machine for knitting on transferred fabric section having needles and web-holders, and means for retracting and for advancing the web-holders, means operating in relation to the retracting means for the Web-holders mounted on the machine in relation to said Web-holder retracting and advancing means and acting ona transferred fabric section during knitting progressively to move the said fabric section on the needles into operative position in respect to subsequently advanced Web-holders.

2. In a circular knitting machine for knitting on transferred fabric section having needles and web-holders, and an internal yarn guiding device mounted above and near the plane of intersection of the needles and the fabric-supporting edges of the Web-holders, and means for retracting and for ad vancing the Web-holders, meansmounted on the internal yarn guiding device in relation to the retracting means for the Web-holders acting 011 a transferred fabric section progrcssively to move the said fabric section on the needles into operative positionat said plane of intersection in respect to subsequently advanced Web-holders.

3. I11 a knitting machine in combination with needles, Web-holders having hold-down hooks, means for advancing the Web-holders and for retrzicting the \vebl1old-ers in a Wave, and a cam at the backs of the needles adapted to act progressively on transferred fabric near the backs of the needles and in respect to re tracted Web-holders to movc'said fabric on the needles into a plane under said hold-down hooks.

4. In a circ'ular knitting machine in combi nation with needles, a removable support for yarn guides, Web-holders having hold-down hooks, means for advancing the web-holders and for retracting the web-holders in a Wave,

and a cam mounted on said removable support and operatively positioned at the backs of the needles and thereby adapted to act ing a wave of motion in needles leveled for transfer and feeding yarn to said needles, Web-holders, means to retract them at retracting needles, and means to advance them, cam means fixed in relation to saidrespective Waves of motion adapted progressively to act on transferred fabric to move it into position for operative contact With web-holders prior to their advance.

6. In a circular knitting machine in combination With needles, yarn-feeding means inclu ding an internal yarn guide device mounted to be moved into and out of operative posi-' tion, Web-holders having hold-down hooks, means foradvancing the Web-holders and for retracting the Web-holders in a wave, and a cam mounted on the internal yarn-guide device adapted when said device is operatively positioned to act at the backs of the needles and progressively on transferred fabric near the backs of the needles and in respect to retracted web-holders to move said fabric down on the needles into a plane'under said hold down hooks. i
